Call for observations on 3 Clasical Be stars: Omi And, Phi A
Posted: Fri Aug 03, 2018 4:57 am
Hello,
here a request rom a professional astronomers team to monitor three taregt with the goal to trigger follow up observations with different instruments in case of discovered outburst:
We would like to request one spectrum per night to be taken for each of the 3 targets at resolution at least 10000, and containing the H-alpha line. As this monitoring is meant as a potential trigger for follow up observations, we ask that the spectra are submitted to the BeSS website as soon as possible after they are taken. We are looking for a sudden increase in line emission or a sudden onset of line wings asymmetry in a previously symmetric profile (i.e., signs an outburst - an ejection of material from the star into its surroundings). In case you can detect a clear increase in emission as compared to the spectra taken previously, please also send an e-mail to robertklement@gmail.com and to the BeSS valid team at webmaster.BeSS@obspm.fr. Thank you!
Cordialement,
Olivier
